Hyukjin Kwon commented on SPARK-27014:
--------------------------------------

2.5.0 is not released and it will be 3.0.0. Also please avoid to set fix 
versions which are usually set when it's actually fixed.

> Support removal of jars and Spark binaries from Mesos driver and executor 
> sandboxes

>                 Key: SPARK-27014
>                 URL: https://issues.apache.org/jira/browse/SPARK-27014
>             Project: Spark
>          Issue Type: New Feature
>          Components: Mesos
>    Affects Versions: 2.5.0
>            Reporter: Martin Loncaric
>            Priority: Minor
>
> Currently, each Spark application run on Mesos leaves behind at least 500MB 
> of data in sandbox directories, coming from Spark binaries and copied URIs. 
> These can build up as a disk leak, causing major issues on Mesos clusters 
> unless their grace period for sandbox directories is very short.
> Spark should have a feature to delete these (from both driver and executor 
> sandboxes) on teardown.
